![]() You’ll just need a minimum throw (the distance between where the projector is and what it’s projecting on to) of 1.5m. At 11kg, it’s probably best suited to a dedicated rack or ceiling mount, but it can shift its image vertically and horizontally to accommodate a less-than-ideal placement if necessary. Remember though, that 4K UST projectors are 4 -5x the cost of pixel-shift 4K short throw projectors, but do not have 4 – 5x the picture quality – these short throw projectors are currently much better value for money.Before you buy it though, you’re going to want to make sure you’ve got the space for it, as it’s a pretty chunky bit of kit. Generally it works well, although comparing any of these pixel-shift 4K projectors to a UST projector with true 4K, you will see a noticeable difference. This is effectively a 1080p image upscaled to 4K, which happens by splitting the input and re-sending it through the image processor. This is a sign of lower quality glass in the lens.Īlso, it should be noted that every 4K projector in this review actually creates the 4K image by pixel shifting, despite many of them being advertised as “true 4K”. Chromatic aberration is where the light is split into different color bands on the edges of shapes, producing a multicolored halo or color fringe around objects.This is usually more noticeable at closer viewing distances, but can be a sign of poor focusing control on the projector. Chromatic dispersion, which refers to light dispersing outside of the intended area, so that on-screen text appears fuzzy, and points of light, like stars, bleed into their surroundings.Overall picture quality is by far the most important part of any 4K short throw projector, but how can you define this?Īlthough every projector in this article has very good clarity, color and sharpness, there are some that are better that others in the details of picture quality, such as chromatic aberration, color fringing, and the rainbow effect, and this is therefore where you can separate models out from one another. Even short throw 4K projectors are quite expensive, so you must be sure that it is worth the high price tag. Can you connect the projector to WiFi, or use Bluetooth to connect to your sound system? Does the projector have Netflix, Disney+ and other streaming apps available natively, or do you have to add a separate streaming stick? Can you setup the projector easily, and does the remote work well for general day-to-day use? If you are in the market for a 4K short throw gaming projector, then frame rate is crucial, as projectors tend to have much more lag than traditional TVs. Brightness is a useful metric, as it lets you know how well a projector performs in a bright room, useful if you want to use it during daytime.Consider native and upscaled 4K, color fringing and contrast, and overall sharpness. You could add many more to this list, such as on-board sound quality, but this metric is fairly uniform across all projectors of this type, so I’ve tried to consider only the most relevant points. ![]() There are a few key characteristics that are useful for comparing short throw 4K projectors, which are what I have used to decide on the projectors reviewed within this article. What Makes the Ideal Short Throw 4K Projector? As an example, if you wanted a 100-inch width picture and were looking at a projector with a 0.5 throw ratio, this means that you would need to place the projector 100 x 0.5 = 50 inches from the screen. ![]() So, to understand how far back from the screen you need to place your projector, simply multiple the throw ratio by the width of the image you want to project. This means that for every inch of screen width, the projector must be 0.4 inches from the screen. You often see throw ratios quoted as just a number, like 0.5, which refers to the ratio 0.5:1. The throw ratio directly refers to how close to the screen the projector must be in order to produce an image, with a lower ratio meaning the projector can be closer. The difference between them is in throw ratio and distance, with short throw projectors having a throw ratio of 0.4 to 1.5, and ultra short throw projectors having a throw ratio below 0.4. Many people use the terms “short throw projector” and “ultra short throw projector” (UST) interchangeably, but these do not refer to the same groups of products. Before we get into the detailed reviews, it pays to define precisely what a short throw projector is.
